NAME FUNCTION
1 1 UVIN3
Undervoltage Threshold Input 3. When the voltage on UVIN3 falls below its threshold, UVOUT3
asserts low.
2 2 OVIN3
Overvoltage Threshold Input 3. When the voltage on OVIN3 rises above its threshold, OVOUT3
asserts low.
3 3 UVIN4
Undervoltage Threshold Input 4. When the voltage on UVIN4 falls below its threshold, UVOUT4
asserts low.
4 4 OVIN4
Overvoltage Threshold Input 4. When the voltage on OVIN4 rises above its threshold, OVOUT4
asserts low.

Unmonitored Power to the Device
78 UVOUT3
Active-Low Undervoltage Output 3. When the voltage at UVIN3 falls below its threshold, UVOUT3
asserts low and stays asserted until the voltage at UVIN3 exceeds its threshold. The open-drain
output has a 30µA internal pullup to V
CC
.
89 OVOUT3
Active-Low Overvoltage Output 3. When the voltage at OVIN3 rises above its threshold, OVOUT3
asserts low and stays asserted until the voltage at OVIN3 falls below its threshold. The open-drain
output has a 30µA internal pullup to V
CC
.
910 UVOUT4
Active-Low Undervoltage Output 4. When the voltage at UVIN4 falls below its threshold, UVOUT4
asserts low and stays asserted until the voltage at UVIN4 exceeds its threshold. The open-drain
output has a 30µA internal pullup to V
CC
.
10 11 OVOUT4
Active-Low Overvoltage Output 4. When the voltage at OVIN4 rises above its threshold, OVOUT4
asserts low and stays asserted until the voltage at OVIN4 falls below its threshold. The open-drain
output has a 30µA internal pullup to V
CC
.
11 14 MARGIN
Active-Low Margin Enable Input. Pull MARGIN low to deassert all outputs (go into high state)
regardless of the voltage at any monitored input.
12 15 OVOUT2
Active-Low Overvoltage Output 2. When the voltage at OVIN2 rises above its threshold, OVOUT2
asserts low and stays asserted until the voltage at OVIN2 falls below its threshold. The open-drain
output has a 30µA internal pullup to V
CC
.
